Try putting the entire contents of the file into a scalar variable and checking that variable for a match on SUCCESS or FAILED. Then assign values to $buildmsg accordingly. Example:

#!/usr/bin/perl
open( FH, "filename" ) || die "No way man\n";

while ( <FH> ) {
    $data .= $_;
}

if ( $data =~ m/failed/i ) {
     $buildmsg = $data;
} else {
     $buildmsg = "BUILD SUCCESSFUL";
}

# continue

I didn't test this but the idea should work. - kel -
